Return of the late 80's ?

Well Rotor rings have been selling for awhile, guess it was time for other to come out also.

 

[Heidi]

I dunno - it has been kicking around forever now.

All it takes is a big name to win with those and they'll be the next biggest thing.

Jens Voight uses them I think.

I almost have man-love for Jens, but I'm not running Q-Rings.

(I wish I were in Morgan Hill to follow Jens around the halls of Spec and be a creepy stalker)

I think it's spelled "JENS!"
Just FYI...

Actually, Osymetrics and Rotor rings work exactly oposite to bio-pace. The theory behing bio pace was to have the lower gear section where the rider could push hardest so that the leg speed would increase to push through the dead spot better. Q rings et al put the higher gear where one can apply more force and the cranks will go faster through the dead spot. I have the q rings on the road bike and you can feel a difference. I can't say that it is faster or easier and I don't think I would get them again.

i thought Bobby Julich was the first pro to use them? look weird but if i remember right he seemed to like them quite a bit. but that could have been sponsor dollars talking too

LOL Next time you need to replace your chainrings, order a set. I don't think that they slow me down any and they probably are more efficient. The only way to really know would be with power meters and tests and stuff. I just ride. I had a 27 X 40 on my mountainbike too. I think rotor rings make more difference at low rpm like when your off road on a steep loose climb and have to remain seated for traction. You do pedal past the top and bottom parts of the pedal stroke faster. And they are adjustable for position. Three positions for the off road version and five for the road.
